I
started to photograph mineral
specimens about 1970 and published my first paper
about
mineral photography in 1974 (in German). Mostly I used my pictures to
illustrate my papers about minerals and collecting them. At
that
time I used a Rolleiflex SL 66 and a Nikon FM camera. But also
others asked me to do that for books and magazines. During
the 1980th and 1990th I did not photograph much,mostly it was a
question of time. Now with the availability of
digital cameras and multilayer software I am more active again. It is
now possible to make
pictures of small crystals which before have been a dream. For objects
smaller than 20 mm I
now photograph using multi focus (multilayer) techniques with
Helicon Focus software and the photo sets shown below.
